I’m looking for an open source image viewer for Windows 10.
ImageGlass seems to be the one recommended, but it requires .NET and Edge WebView2 Runtime, which is not open source(ImageGlass 9.2.0.1208 - Maroon 4 | ImageGlass). And those runtimes do not come along preinstalled with the Windows 10 LTSC (both IoT and non-IoT).
There have been some issues with the ImageGlass code that could damage users’ privacy. Even though it was swiftly removed afterward, as a former ImageGlass user, the incident has left a sour taste in my mouth regarding the developer.
There’s digiKam from KDE. nomacs is one of the older, but still relatively popular options. Although there have been some issues with maintaining the project, it seems that the program still receives some support from new maintainers, who have recently published several beta releases.
